Abstract
OBJECTIVE To evaluate the effect of socioeconomic and demographic factors on outcomes in rhegmatogenous retinal detachments (RRDs). DESIGN Retrospective cohort study. METHODS A total of 71 white and 124 black and/or Hispanic patients who had surgical repair of RRDs between October 2013 and September 2021 at a single-centre safety net hospital. Main outcomes were single surgery success rates (SSSR) and postoperative visual acuity at 6-month and final follow-up. RESULTS Black and (or) Hispanic patients were significantly younger (black and [or] Hispanic, 50.7 years vs white, 57.6 years; p = 0.003), had lower mean household incomes (black and [or] Hispanic, $80,932 vs white, $92,911; p = 0.007), were more likely to have more than 1 retinal break (black and [or] Hispanic, 65% vs white, 49%; p = 0.04), and had higher rates of proliferative vitreoretinopathy (PVR) at presentation (black and [or] Hispanic, 35% vs white, 18%; p = 0.02). SSSR was similar (black and [or] Hispanic, 73.4% vs white, 73.2%; p = 0.98), but black and (or) Hispanic patients had worse visual acuity postoperatively (black and [or] Hispanic, 20/63 vs white, 20/40 at final follow-up; p = 0.03). While race was linked to visual outcome in univariate testing; multivariate analysis revealed only macula status (p = 0.007 at 6 months; p = 0.01 at final follow-up), presence of PVR (p < 0.001 at both time points), and SSSR (p = 0.003 at final follow-up) as predictors of worse visual outcomes. CONCLUSIONS Preoperative factors such as higher rates of PVR may contribute to worse vision outcomes in black and (or) Hispanic patients undergoing surgical repair for RRD.

Abstract
Purpose Long-term patient satisfaction may influence patients' perspectives of the quality of care and their relationship with their providers. This is a follow up to a comparative effectiveness study investigating oral to intravenous sedation (OIV study). The OIV study found that oral sedation was noninferior in patient satisfaction to standard intravenous (IV) sedation for anterior segment and vitreoretinal surgeries. This study aims to determine if patient satisfaction with oral sedation remained noninferior long term. Patients and Methods Patients were re-interviewed using the same satisfaction survey given during the OIV study. Statistical analysis involved t-tests for noninferiority of the long-term mean satisfaction score of oral and IV sedation. We also compared the original mean satisfaction score and the follow-up mean satisfaction score for each type of sedation and for both groups combined. Results Participants were interviewed at a median of 1225.5 days (range 754-1675 days) from their surgery. The original mean satisfaction score was 5.26 ± 0.79 for the oral treatment group (n = 52) and 5.27 ± 0.64 for the intravenous treatment group (n = 46), demonstrating noninferiority with a difference in mean satisfaction score of 0.015 (p < 0.0001). The follow-up mean satisfaction score was 5.23 ± 0.90 for oral sedation and 5.60 ± 0.61 for IV sedation, with a difference in the mean satisfaction score of 0.371 (p = 0.2071). Satisfaction scores did not differ between the original mean satisfaction score and the follow-up mean satisfaction score for the oral treatment group alone (p = 0.8367), but scores in the intravenous treatment group increased longitudinally (p = 0.0004). Conclusion In this study, long-term patient satisfaction with oral sedation was not noninferior to satisfaction with IV sedation, unlike our findings with short-term patient satisfaction in our original study. Patient satisfaction also remained unchanged over time for the oral treatment group, but patients in the intravenous treatment group reported higher long-term satisfaction with their anesthesia experience compared to the immediate post-operative period.

Abstract
Background: The purpose of this research was to compare patient satisfaction between hybrid ophthalmology telemedicine and standard-of-care in-person visits. A retrospective, cross-sectional, case-control analysis of patient satisfaction based on survey data was used. Methods: Responses to the National Research Council Health Patient Survey were retrieved for randomly sampled hybrid ophthalmology telemedicine and in-person visits between March 11, 2020 and December 31, 2021 at a hospital-based eye clinic in Boston, Massachusetts. The primary outcome was based on the question "How likely would you be to recommend this provider to your family and friends?" (0-10 scale) with a score of 9 or 10 coded as satisfied. Two-sample t-tests, Pearson's chi-square tests, and bivariate logistic regressions were used to compare patient satisfaction scores between the hybrid and in-person cohorts. Demographic data, including age, sex, language, and self-reported race and ethnicity, were used as potential predictors of patient satisfaction in a multivariable logistic regression model. Results: There were 49 surveys from hybrid visits and 3,390 surveys from in-person visits. Hybrid visit patients reported high satisfaction scores without significant differences compared to in-person visit patients (hybrid 79% satisfied, in-person 82% satisfied, p = 0.728). Age was significantly associated with satisfaction in the hybrid cohort with the 65+ age group reporting lower satisfaction (below 65 years 100% satisfied, 65+ years 60% satisfied, p = 0.003). No association with age was observed in the in-person cohort. Conclusions: The hybrid ophthalmology telemedicine model can provide effective care without sacrificing patient satisfaction. Older patients may benefit from targeted interventions in future telemedicine models.

Abstract
Importance Several ophthalmic diseases disproportionately affect racial and ethnic minority patients, yet most clinical trials struggle to enroll cohorts that are demographically representative of disease burden; some barriers to recruitment include time and transportation, language and cultural differences, and fear and mistrust of research due to historical abuses. Incorporating diversity within the research team has been proposed as a method to increase trust and improve engagement among potential study participants. Objective To examine how demographic factors of potential research participants and personnel may be associated with patient consent rates to participate in prospective ophthalmic clinical studies. Design, Setting, and Participants This retrospective cohort study included patients from an urban, academic hospital who were approached for consent to participate in prospective ophthalmic clinical studies conducted between January 2015 and December 2021. Main Outcomes and Measures Multivariable logistic regression assessing associations between patient and research personnel demographics and rates of affirmative consent to participate was used. Results In total, 1380 patients (mean [SD] age, 58.6 [14.9] years; 50.3% male) who were approached for consent to participate in 10 prospective ophthalmic clinical studies were included. Of prospective patients, 566 (43.5%) were Black; 327 (25.1%), Hispanic or Latino; 373 (28.6%), White; 36 (2.8%), other race and ethnicity; and 78 (5.8%) declined to answer. Black patients (odds ratio [OR], 0.32; 95% CI, 0.24-0.44; P < .001) and Hispanic or Latino patients (OR, 0.31; 95% CI, 0.20-0.47; P < .001) were less likely to consent compared with White patients. Patients with lower socioeconomic status were less likely to consent than patients with higher socioeconomic status (OR, 0.43; 95% CI, 0.33-0.53; P < .001). Concordance between patient and research staff race and ethnicity was associated with increased odds of affirmative consent (OR, 2.72; 95% CI, 1.99-3.73; P < .001). Conclusions and Relevance In this cohort study, patients from underrepresented racial and ethnic groups and those with lower socioeconomic status were less likely to participate in ophthalmic clinical studies. Concordance of race and ethnicity between patients and research staff was associated with improved participant enrollment. These findings underscore the importance of increasing diversity in clinical research teams to improve racial and ethnic representation in clinical studies.

Abstract
Purpose: To determine the effects of socioeconomic factors on visit adherence and the resultant visual outcomes for patients receiving intravitreal injections for neovascular age-related macular degeneration during the COVID-19 pandemic. Methods: In this retrospective case-control study, medical records were reviewed to collect appointment attendance, age, sex, self-reported race/ethnicity, primary language, marital status, insurance, distance from clinic, and Area Deprivation Index (ADI), a measure of socioeconomic disadvantage. Multivariate regression models were created to determine differences in socioeconomic factors between individuals who attended (show group) and those who did not attend (no-show group) appointments. Results: The study enrolled 126 patients in the show group and 115 in the no-show group. On univariate analysis, nonadherence was significantly higher in non-White patients than in White patients (P = .04), urban sites than in suburban sites (P = 1.7 × 10-4), and non-English-speaking patients than in English-speaking patients (P = 4.0 × 10-3). The associations remained significant in multivariate analysis for non-English-speaking patients (P = .03) and urban-site patients (P = .01) after adjusting for age, sex, self-reported race/ethnicity, primary language, marital status, insurance, distance from clinic, site of visit, and ADI. At 6 months and 1 year, a 1-, 2-, and 3-line vision loss was significantly higher in the no-show group than in the show group on univariate and multivariate analysis after adjusting for age, sex, race, lens status, and presence of glaucoma and diabetic retinopathy. Conclusions: Non-English-speaking patients and urban-based patients were less likely to present for intravitreal injection appointments during the initial peak of the COVID-19 pandemic. This disparity translated to worse vision outcomes at 6 months and 1 year.

Abstract
A 37-year-old Hispanic male with a recent history of COVID-19 infection and type 2 diabetes mellitus was admitted to the hospital with shortness of breath, chest pain, and hyperglycemia. Eye exam and imaging findings indicated endogenous endophthalmitis confirmed by blood cultures that speciated to Klebsiella pneuomoniae. The patient's eye condition progressed, ultimately resulting in no light perception less than a month after the initial evaluation. Due to the rapidly progressive nature of Klebsiella endogenous endophthalmitis, we recommend that primary teams consult ophthalmology for close monitoring of patients with a high index of suspicion.

Abstract
BACKGROUND Patients with eye disease have an increased risk for developing neurodegenerative disease. Neurodegenerative proteins can be measured in the eye; however, correlations between biomarker levels in eye fluid and neuropathological diagnoses have not been established. OBJECTIVE This exploratory, retrospective study examined vitreous humor from 41 postmortem eyes and brain tissue with neuropathological diagnoses of Alzheimer's disease (AD, n = 7), chronic traumatic encephalopathy (CTE, n = 15), both AD + CTE (n = 10), and without significant neuropathology (controls, n = 9). METHODS Protein biomarkers i.e., amyloid-β (Aβ 40,42), total tau (tTau), phosphorylated tau (pTau181,231), neurofilament light chain (NfL), and eotaxin-1 were quantitatively measured by immunoassay. Non-parametric tests were used to compare vitreous biomarker levels between groups. Spearman's rank correlation tests were used to correlate biomarker levels in vitreous and cortical tissue. The level of significance was set to α= 0.10. RESULTS In pairwise comparisons, tTau levels were significantly increased in AD and CTE groups versus controls (p = 0.08 for both) as well as AD versus AD+CTE group and CTE versus AD+CTE group (p = 0.049 for both). Vitreous NfL levels were significantly increased in low CTE (Stage I/II) versus no CTE (p = 0.096) and in low CTE versus high CTE stage (p = 0.03). Vitreous and cortical tissue levels of pTau 231 (p = 0.02, r = 0.38) and t-Tau (p = 0.04, r = -0.34) were significantly correlated. CONCLUSION The postmortem vitreous humor biomarker levels significantly correlate with AD and CTE pathology in corresponding brains, while vitreous NfL was correlated with the CTE staging. This exploratory study indicates that biomarkers in the vitreous humor may serve as a proxy for neuropathological disease.

Abstract
PURPOSE To determine the long-term incidence of and risk factors for delayed retinal tears after acute, symptomatic posterior vitreous detachment (PVD) without concurrent retinal tears. DESIGN Retrospective, observational case series. SUBJECTS Patients diagnosed with an acute, symptomatic PVD without concurrent retinal tears at a tertiary eye center between 2013 and 2018. METHODS This is a retrospective, consecutive, and observational case series. Acute and symptomatic PVD was defined as experiencing flashes or floaters for 1 month or less at the time of diagnosis. Patients with a retinal tear or detachment at or before the time of diagnosis were not included. The occurrence and timing of subsequent retinal tears after initial PVD diagnosis were recorded. The age, sex, race, refractive error, lens status, lattice degeneration status, and type of physician (retina specialist vs. nonretina specialist) who saw the patient were also recorded. MAIN OUTCOME MEASURES Time to the development of a delayed retinal tear. RESULTS A total of 389 eyes from 389 patients had acute and symptomatic PVDs without concurrent retinal tears or detachments at diagnosis. Kaplan-Meier analysis showed that 7.39% of eyes developed delayed retinal tears by 6.24 years after initial PVD diagnosis. Of these tears, 50% occurred within 4.63 months of PVD diagnosis, and 63.46% occurred within 1 year of PVD diagnosis. Cox-Mantel log-rank analysis showed that those who were younger (age < 60 years), myopic, or had lattice degeneration were more likely to develop tears. A multivariate Cox proportional-hazards models controlling for other significant risk factors supported lattice degeneration as a likely risk factor for delayed retinal tear. CONCLUSIONS This study demonstrates that 7.39% of patients with acute, symptomatic PVD without concurrent retinal tears develop delayed retinal tears by 6.24 years after PVD diagnosis, with many developing tears well after a typical 6-week follow-up time for PVD. Lattice degeneration is a significant risk factor for delayed tears. These findings can guide clinicians in establishing optimal follow-up protocols for patients with acute, symptomatic PVD.

Abstract
Abstract
Purpose The H-index (Hi), an author-level metric of scholarly impact, is predictive of future scientific achievement. We sought to analyze the scholarly impact of student authorship on the Hi of corresponding authors (CAs) within a major academic journal in the specialty of ophthalmology.
Materials and Methods We compared the Hi of all unique CAs for manuscripts published in Ophthalmology (Journal of the American Academy of Ophthalmology) in 2008, 2012, and 2016. Data abstraction was completed twice: in October 2018 and March 2021. We further grouped published articles for CAs into those with student authors (StA) and those without (nStA). Primary analysis involved a linear regression analysis with change in Hi from October 2018 to March 2021 as the outcome variable, CA groups as the predictor variable, adjusting for the covariates of baseline Hi, the year when the CA published his or her article, number of research items published in October 2018, and the academic appointment of the CAs. Secondary analysis involved a linear regression analysis with change in Hi from October 2018 to March 2021 as the outcome variable, total number of student authors per CA as the predictor variable, adjusting for the covariates of baseline Hi, the year CA published his or her article, number of research items published in October 2018, and the academic appointment of the CAs.
Results The number of student authors increased from 168 in 2008 to 192 in 2016. Of the 902 articles, 316 articles were co-authored by one or more student authors. The average change in Hi of CAs publishing with student authors (StA, 11.0 ± 14.7) was significantly greater (p < 0.0001) than the change in Hi of CAs publishing without student authors (nStA, 6.2 ± 6.2). As the total number of student authors increased, the change in Hi of CAs increased linearly for all years combined (regression coefficient = 1.70, p-value < 0.0001).
Conclusion CAs publishing with students in the field of ophthalmology have a higher scholarly impact than those publishing without students. The development of programs to integrate students into ophthalmology research early on may encourage their pursuit of a career in ophthalmology, while advancing the careers of their mentors.

Abstract
The purpose of this study is to characterize the inflammatory cytokine profile in rhegmatogenous retinal detachments (RRDs) compared to surgical controls. Vitreous humor was collected from patients undergoing vitrectomy for RRD and noninflammatory vitreoretinal diseases. A quantitative immunoassay was used to measure the levels of 36 cytokine markers. Linear regression analysis with the duration of detachment as the predictor and log-transformed cytokine levels as the outcome was conducted for normally distributed cytokines as determined by the Shapiro-Wilk test. The analysis was adjusted for age, sex, and race. The Kruskal-Wallis test was used for cytokines not normally distributed. Twenty-seven RRD cases and thirteen control cases were studied. Between all RRDs and controls, fibroblast growth factor 2 (FGF2) (p = 0.0029), inducible protein-10(IP-10) (p = 0.0021), monocyte chemoattractant protein-1 (MCP-1) (p = 0.0040), interleukin (IL)-16 (p = 0.018), IL-8 (p = 0.0148), IL-6 (p = 0.0071), eotaxin (p = 0.0323), macrophage inflammatory protein (MIP)-1 alpha (p = 0.0149), MIP-1 beta (p = 0.0032), and the thymus and activation regulated cytokine (TARC) (p = 0.0121) were elevated in RRD cases. Between acute RRDs (n = 16) and controls, FGF2 (p = 0.0001), IP10 (p = 0.0027), MCP-1 (p = 0.0015), MIP-1β (p = 0.0004), IL-8 (p = 0.0146), and IL-6 (p = 0.0031) were elevated. Determining alterations in inflammatory cytokine profiles may aid in understanding their impact on RRD development, clinical course, and complications before and after surgical repair.

Abstract
Age-related macular degeneration (AMD) has been implicated as a risk factor for severe consequences from COVID-19. We evaluated the genetic architecture shared between AMD and COVID-19 (critical illness, hospitalization, and infections) using analyses of genetic correlations and pleiotropy (i.e., cross-phenotype meta-analysis) of AMD (n = 33,976) and COVID-19 (n ≥ 1,388,342) and subsequent analyses including expression quantitative trait locus (eQTL), differential gene expression, and Mendelian randomization (MR). We observed a significant genetic correlation between AMD and COVID-19 infection (rG = 0.10, p = 0.02) and identified novel genome-wide significant associations near PDGFB (best SNP: rs130651; p = 2.4 × 10-8) in the pleiotropy analysis of the two diseases. The disease-risk allele of rs130651 was significantly associated with increased gene expression levels of PDGFB in multiple tissues (best eQTL p = 1.8 × 10-11 in whole blood) and immune cells (best eQTL p = 7.1 × 10-20 in T-cells). PDGFB expression was observed to be higher in AMD cases than AMD controls {fold change (FC) = 1.02; p = 0.067}, as well as in the peak COVID-19 symptom stage (11-20 days after the symptom onset) compared to early/progressive stage (0-10 days) among COVID-19 patients over age 40 (FC = 2.17; p = 0.03) and age 50 (FC = 2.15; p = 0.04). Our MR analysis found that the liability of AMD risk derived from complement system dysfunction {OR (95% CI); hospitalization = 1.02 (1.01-1.03), infection = 1.02 (1.01-1.03) and increased levels of serum cytokine PDGF-BB {β (95% CI); critical illness = 0.07 (0.02-0.11)} are significantly associated with COVID-19 outcomes. Our study demonstrated that the liability of AMD is associated with an increased risk of COVID-19, and PDGFB may be responsible for the severe COVID-19 outcomes among AMD patients.

Abstract
This case series examines visual and anatomic outcomes of focal laser photocoagulation in the treatment of central serous chorioretinopathy (CSCR) with subretinal fluid (SRF) in under-represented populations. We reviewed records of 25 eyes with CSCR and SRF that underwent focal laser photocoagulation. Visual acuity (VA) and central macular thickness (CMT) were recorded prior to laser, after laser treatment, and at final follow-up and were all compared using Wilcox signed-rank tests after using Shapiro-Wilk tests to determine normality. The racial and ethnic breakdown of our cohort (n = 25) includes 64% Hispanic (n = 16), 20% black (n = 5), 12% Asian (n = 3), 4% other (n = 1). Patients were followed for a median of 15.5 months (range: 5.75-87 months) after treatment. The VA prior to laser compared to best-available VA significantly improved (p = 0.0003). Pre-laser CMT to post-laser CMT (p < 0.0001) and pre-laser CMT to final CMT (p < 0.0001) significantly improved. Excluding the one eye that developed a choroidal neovascular membrane, the pre-laser VA to final VA improved significantly (p = 0.0047) as well as the pre-laser CMT to final CMT (p < 0.0001). Of the 25 eyes, 4 had persistent SRF following laser, and of the 21 eyes with complete resolution of SRF, 2 developed recurrent SRF. Focal laser photocoagulation can significantly improve VA and CMT in CSCR with active SRF in patients who have been under-represented in prior clinical studies.

Abstract
IMPORTANCE The hybrid ophthalmology telemedicine model asynchronously pairs an imaging appointment by a technician with a subsequent virtual appointment by a clinician. Although it has been mentioned in several studies as an alternative to standard in-person care during the COVID-19 pandemic, outcomes of this alternative clinical care model remain to be evaluated. OBJECTIVE To investigate the outcomes associated with the hybrid ophthalmology telemedicine model during the COVID-19 pandemic for nonurgent and nonprocedural ophthalmological care. DESIGN, SETTING, AND PARTICIPANTS Retrospective, cross-sectional study of all hybrid visits scheduled during the year 2020 in a single academic, hospital-based eye clinic in Boston, Massachusetts. All hybrid ophthalmology telemedicine visits completed in the year 2020 by opthalmologists and optometrists were included. Data were analyzed from January to December 2020. EXPOSURES Hybrid telemedicine clinical encounters. MAIN OUTCOMES AND MEASURES Four outcome metrics were calculated: (1) need for subsequent procedure visit, (2) medication change, (3) nonurgent, and (4) urgent consultation with another eye clinician. Adverse outcomes were defined as irreversible vision loss and the need for additional in-person evaluation to reach a management decision. RESULTS From April 9 to December 30, 2020, 889 patients (506 female patients [56.9%]; mean [SD] age, 62.1 [14.5] years; age range, 13-98 years) completed 940 hybrid visits. The most common visit indications were glaucoma (424 visits [45.1%]) and retinal diseases (499 visits [53.1%]). A total of 25 visits (2.7%) led to a procedure, 22 visits (2.3%) led to a change in medication, and 44 visits (4.7%) were referred for nonurgent consultation with another subspecialty with no instances of urgent referrals. Sixteen patients (1.7%) were referred to the on-call clinician for a same-day emergency in-person visit or recommended for a subsequent standard in-person visit to reach a management decision. There were no cases of irreversible vision loss following a hybrid visit. CONCLUSIONS AND RELEVANCE These findings suggest that with the appropriate patient selection and clinical setting, the hybrid ophthalmology telemedicine model may be a good alternative to standard in-person visits, particularly for patients with glaucoma and retinal diseases.

Abstract
Purpose: This work aims to determine whether patient satisfaction with oral sedation is noninferior to intravenous (IV) sedation in vitrectomy surgery. Methods: This prospective, randomized, double-masked, noninferiority clinical trial measured patient satisfaction in 84 participants receiving oral or IV sedation during vitrectomy surgery under monitored anesthesia care. Patients were excluded if they were unable to receive benzodiazepines. Results: The primary outcome was patient satisfaction. Secondary outcomes included surgeon and anesthesia provider satisfaction, need for supplemental anesthesia, and surgical complications. Among the 84 patients (46 [54.8%] men; mean [SD] age, 57.0 [12.7 years]), mean patient satisfaction scores were 5.22 ± 0.81 (range, 3.08-6; scale 1-6) with oral and 5.25 ± 0.63 (range, 3.83-6; scale 1-6) with IV sedation. With an a priori noninferiority margin of 0.5 and a difference in mean scores between the groups of 0.03 (1-tailed 95% CI, infinity to 0.29), our results demonstrated the noninferiority of oral sedation ( P = .002). There were no significant differences in surgeon or anesthesia satisfaction or major intraoperative complications. Five patients receiving oral (11.9%) and 3 receiving IV (7.1%) sedation required supplemental IV sedation (difference, 4.8%; P = .46). Conclusions: Patient satisfaction for oral sedation was noninferior to IV sedation for vitrectomy surgery.

Abstract
Purpose This secondary analysis of a clinical trial that measured surgeon, anesthesiologist, and patient satisfaction following ophthalmic surgery under monitored anesthesia care (MAC) with a benzodiazepine investigates the degree of association between patient satisfaction with anesthesia compared to surgeon and anesthesiologist satisfaction with anesthesia. Patients and Methods Data from analogous 6-point surgeon satisfaction surveys and anesthesiologist satisfaction surveys were compared to data from a 6-point validated patient satisfaction survey collected from a clinical trial investigating satisfaction with different forms of benzodiazepine for patients undergoing cataract, retina, cornea, or glaucoma surgery. Relationships between measures were analyzed using Pearson’s correlation coefficient, with further subgroup analysis based on language groups and single-question measures of satisfaction. Results A total of 283 ophthalmic surgical cases were analyzed. Mean surgeon satisfaction was 5.27 (range, 1.33–6.00), mean anesthesiologist satisfaction was 5.12 (range, 1.17–6.00), and mean patient satisfaction was 5.28 (range, 2.58–6.00). The correlation between surgeon and patient satisfaction was 0.333 (p = 9.06e-9), while the correlation between anesthesiologist and patient satisfaction was 0.319 (p = 4.28e-8). There was no difference between English and non-English speaking patients in correlation between surgeon and patient satisfaction (p = 0.08) and anesthesiologist and patient satisfaction (p = 0.47). Conclusion The data demonstrate a low level of association between patient satisfaction with anesthesia and provider satisfaction, even when patient language is taken into consideration. This suggests that providers are poor predictors of patient satisfaction with anesthesia and are unreliable judges of patient comfort perioperatively.

Abstract
A dual-channel optical coherence tomography system with wavelengths in the visible and near-infrared light ranges can provide both structural and functional information for retinal microvasculature simultaneously. We applied this integrated system in an ongoing clinical study of patients with various retinal pathologies. Here, we present case study results of patients with diabetic retinopathy, central retinal vein occlusion, and sickle cell retinopathy compared to a healthy subject. For the first time, this comparison validates the system's ability to detect structural anomalies in both en face and B-scan images with simultaneous retinal optical coherence tomography angiography and measurement of sO2 in parafoveal vessels that are around 20-30 µm in diameter. This integrated system represents a powerful instrument with potentially far-reaching clinical implications for the early detection and diagnosis of retinal vascular diseases.

Abstract
Degenerative retinoschisis is a common condition characterized by elevation of the inner layers of the peripheral retina. While uncomplicated retinoschisis (i.e. with no associated retinal layer breaks) is almost invariably a benign process, retinal detachment associated with isolated outer layer breaks (termed schisis-detachment) is fairly common. Historically, schisis-detachment has been treated with a variety of interventions ranging from retinopexy to intraocular surgery. Based on published descriptions of the natural history of the disease, these interventions are likely unnecessary in many cases and may place the patient's vision at unnecessary risk. Progressive symptomatic schisis-related retinal detachment, on the other hand, is a vision threatening condition that requires intervention. While clinical examination remains the mainstay of diagnosis, recent advances in multimodal imaging can provide supplemental information in subtle cases and may prove valuable for long-term disease monitoring. When evaluating patients with peripheral retinal elevation, it is important for ophthalmologists to make an accurate diagnosis and understand the risk-benefit ratio associated with intervention. Thus, we summarize the current literature on the natural history, clinical and imaging diagnosis, and surgical management of degenerative retinoschisis and its related complications.

Abstract
Purpose To report a case of aggressive chorioretinal paracoccidioidomycosis requiring treatment with systemic antifungal agents, frequent intravitreal voriconazole injections, and surgical excision. Observations A Brazilian man in his mid-30s with a history of chronic, biopsy-proven cutaneous paracoccidioidomycosis, chronic sinusitis, and perichondritis secondary to paracoccidioidomycosis presented with profound vision loss. He was found to have significant vitreous inflammation and a large chorioretinal lesion in the posterior pole concerning for ocular involvement. He was treated initially with combined topical and systemic steroids as well as systemic antifungals and antibiotics, then with serial intravitreal voriconazole injections resulting in a significant reduction of intraocular inflammation and subretinal fluid. The residual tractional retinal detachment from the chorioretinal lesion was addressed surgically by pars plana vitrectomy. Conclusion and importance Intravitreal voriconazole can be an effective adjuvant treatment for the vitreous inflammation and subretinal fluid associated with chorioretinal paracoccidioidomycosis. Surgical intervention may be indicated in cases complicated by tractional retinal detachment.

Abstract
Alzheimer's disease (AD) is one of the most common causes of dementia worldwide. Although no formal curative therapy exists for the treatment of AD, considerable research has been performed to identify biomarkers for early detection of this disease, and thus improved subsequent management. Given that the eye can be examined and imaged non-invasively with relative ease, it has emerged as an exciting area of research for evidence of biomarkers and to aid in the early diagnosis of AD. This review explores the current understanding of both protein and retinal imaging biomarkers in the eye. Herein, primary findings in the literature regarding AD biomarkers associated with the lens, retina, and other ocular structures are reviewed.

Abstract
PURPOSE To identify risk factors for fellow eye treatment of diabetic retinopathy with Vascular Endothelial Growth Factor (VEGF) injections during the Diabetic Retinopathy Clinical Research Network (DRCR.Net) Protocol T trial METHODS: In this post-hoc analysis of randomized clinical trial data, Cox regression analysis was performed at 52 and 104 weeks to determine risk factors for treatment in 360 fellow eyes. Survival analysis was performed to determine mean time to treatment based upon medication used. RESULTS Of 360 fellow eyes, 142 (39.4%) required treatment between weeks 4 and 104. Risk factors predicting a lower likelihood of year 1 treatment included older subject age (Hazard Ratio [HR]=0.98, 95% CI 0.96-0.99; p = 0.02) and higher baseline study eye ETDRS score (HR=0.98, 95% CI 0.97-0.99, p = 0.04). Center-involving DME at baseline in the fellow eye was predictive of a higher treatment need at both 52 (HR=1.89, 95% CI 1.42-2.51, p < 0.0001) and 104 weeks (HR=2.68, 95% CI 1.75-4.11, p < 0.0001). Subjects treated in the study eye with aflibercept (HR=0.574, 95% CI 0.371-0.887, p = 0.013) and ranibizumab (HR=0.58, 95%CI 0.36-0.94, p = 0.03) were less likely to require first year fellow eye injection than subjects treated with bevacizumab although this difference was no longer significant at week 104 (aflibercept HR=0.77, 95% CI 0.52-1.16, p = 0.21; ranibizumab HR=0.66, 95% CI 0.43-1.00, p = 0.05). Mean time to treatment was significantly shorter in the bevacizumab group (bevacizumab 25.83 weeks, aflibercept 38.75 weeks, ranibizumab 34.70 weeks (p=0.012)). CONCLUSION Bilateral treatment with intravitreal anti-VEGF injections was common during the DRCR.net Protocol T. Medication choice may impact the risk of fellow eye treatment.

Abstract
PURPOSE To determine the impact of race and ethnicity on efficacy of intravitreal bevacizumab for diabetic macular edema in anti-vascular endothelial growth factor (VEGF) treatment-naive patients. DESIGN Retrospective cohort study. METHODS Setting: Urban-based academic institution with affiliated private offices. STUDY POPULATION Intravitreal anti-VEGF naïve patients seen between 2010 and 2019 of White (W) race, Black (B) race, or Hispanic (H) ethnicity aged 18 years and older with diabetic macular edema who received intravitreal injections of bevacizumab. Exclusion criteria were prior intravitreal anti-VEGF treatment, invasive ophthalmologic interventions, and laser treatments within 3 months prior to first injection through the duration of the study. Exposures: Intravitreal bevacizumab. MAIN OUTCOMES MEASURES Percentage of patients with visual acuity (VA) improvement and mean percentage reduction in central macular thickness (CMT). RESULTS Percentage with VA improvement was 27% vs 39% vs 50% after 1 injection (n = 314), and 34% vs 55% vs 59% after 3 injections (n = 150) for B, H, and W cohorts, respectively. Black patients experienced lower odds of VA improvement compared with White and Hispanic patients after 1 injection (odds of 0.480, CI 0.284-0.814, P = .006) and 3 injections (odds of 0.342, CI 0.149-0.782, P = .008) while controlling for age, sex, baseline glycated hemoglobin (HbA1c), baseline CMT, baseline VA, laser history, injection time course, and follow-up delay. CONCLUSIONS Black patients had a significantly lower likelihood of visual acuity improvement following intravitreal bevacizumab treatment compared with White and Hispanic patients. Further research is warranted to understand the effect of race and ethnicity on anti-VEGF efficacy to ensure optimal treatment for each individual.

Abstract
BACKGROUND Neurofilament light chain (NfL) is a promising biomarker of neurodegeneration in the cerebrospinal fluid and blood. This study investigated the presence of NfL in the vitreous humor and its associations with amyloid beta, tau, inflammatory cytokines and vascular proteins, apolipoprotein E (APOE) genotypes, Mini-Mental State Examination (MMSE) scores, systemic disease, and ophthalmic diseases. METHODS This is a single-site, prospective, cross-sectional cohort study. Undiluted vitreous fluid (0.5-1.0 mL) was aspirated during vitrectomy, and whole blood was drawn for APOE genotyping. NfL, amyloid beta (Aβ), total Tau (t-Tau), phosphorylated Tau (p-Tau181), inflammatory cytokines, chemokines, and vascular proteins in the vitreous were quantitatively measured by immunoassay. The main outcome measures were the detection of NfL levels in the vitreous humor and its associations with the aforementioned proteins. Linear regression was used to test the associations of NfL with other proteins, APOE genotypes, MMSE scores, and ophthalmic and systemic diseases after adjustment for age, sex, education level, and other eye diseases. RESULTS NfL was detected in all 77 vitreous samples. NfL was not found to be associated with ophthalmic conditions, APOE genotypes, MMSE scores, or systemic disease (p > 0.05). NfL levels were positively associated with increased vitreous levels of Aβ40 (p = 7.7 × 10-5), Aβ42 (p = 2.8 × 10-4), and t-tau (p = 5.5 × 10-7), but not with p-tau181 (p = 0.53). NfL also had significant associations with inflammatory cytokines such as interleukin-15 (IL-15, p = 5.3 × 10-4), IL-16 (p = 2.2 × 10-4), monocyte chemoattractant protein-1 (MCP1, p = 4.1 × 10-4), and vascular proteins such as vascular endothelial growth factor receptor-1 (VEGFR1, p = 2.9 × 10-6), Vegf-C (p = 8.6 × 10-6), vascular cell adhesion molecule-1 (VCAM-1, p = 5.0 × 10-4), Tie-2 (p = 6.3 × 10-4), and intracellular adhesion molecular-1 (ICAM-1, p = 1.6 × 10-4). CONCLUSION NfL is detectable in the vitreous humor of the eye and significantly associated with amyloid beta, t-tau, and select inflammatory and vascular proteins in the vitreous. Additionally, NfL was not associated with patients' clinical eye condition. Our results serve as a foundation for further investigation of NfL in the ocular fluids to inform us about the potential utility of its presence in the eye.

Abstract
PURPOSE A majority of phakic patients undergoing pars plana vitrectomy for epiretinal membrane or macular hole require subsequent cataract surgery within 1-2 years. Combined phaco-vitrectomy eliminates the need for a second surgery and may enable patients to attain their best vision sooner. This study aims to compare the visual outcomes, complication rates, and costs of combined phaco-vitrectomy versus sequential vitrectomy followed by cataract surgery. METHODS Records were searched by CPT® codes to identify patients with both cataract and vitrectomy surgery at our institution over a 5-year period (2013-2018). Chart review included medical history, demographics, exam findings, operating room records, visual acuity (VA), and clinical outcomes. Statistical analyses were performed with SPSS v19 (IBM). Area under the curve for visual acuity was calculated as the trapezoidal mean of the change in Early Treatment of Diabetic Retinopathy Study letters. RESULTS After exclusion, 81 eyes of 78 patients underwent both cataract and vitrectomy surgeries at our institution. Thirty-four eyes underwent separate, sequential vitrectomy then phacoemulsification surgery, and 47 eyes had combined phaco-vitrectomy surgery. Total operating room times (120.81 ± 3.41 vs 161.03 ± 5.45 min; p < 0.0001) and associated costs were significantly lower in the combined surgery compared with those in the sequential surgery group. Baseline and final visual acuity were similar between the two groups. Baseline VA was 35.53 letters (~ 20/200) and 32.81 letters (~ 20/220) and increased to final VA of 63.74 (~ 20/53) and 60.91 letters (~ 20/61), in the sequential and combined groups respectively. Area under the curve for vision was greater in the combined surgery group, with subjects gaining an average of + 9.11 ± 3.32 letters from sequential surgery, and + 19.53 ± 3.53 letters in the combined surgery group (p = 0.04). Additionally, patients in the combined group attained their best visual acuity 449 days (15 months) sooner than those receiving sequential surgery. CONCLUSIONS Combined phaco-vitrectomy surgery resulted in greater area under the curve visual acuity benefit and attainment of best visual acuity 15 months sooner compared with conventional sequential surgeries. There were no significant differences in complication rates or clinical outcomes between the groups, but operative times and costs were lower for combined surgery, supporting a favorable cost-benefit ratio.

Abstract
BACKGROUND The eye may serve as source for diagnostic testing for early detection of Alzheimer's disease (AD). Examination of amyloid-β (Aβ) and tau protein content in human vitreous and its correlation to neuro-cognition may improve ocular-based AD detection methods. OBJECTIVE To evaluate levels of Aβ and tau protein in human vitreous humor and investigate the clinical predictive role of these proteins as early diagnostic markers of AD. METHODS A prospective, single-center, multi-surgeon cohort study. Vitreous humor samples from 80 eyes were measured quantitatively for Aβ40-42, pTau, and tTau. Linear regression was used to test associations between AD biomarker levels, Mini-Mental State Exam (MMSE), and serum apolipoprotein E (APOE) allele status, with adjustment for age, sex, and education level of patients. RESULTS Lower MMSE scores were significantly associated with lower levels of vitreous Aβ40 (p = 0.015), Aβ42 (p = 0.0066), and tTau (p = 0.0085), and these biomarkers were not associated with any pre-existing eye conditions. Presence of the ɛ4 allele and the ɛ2 allele approached significance with reduced Aβ40 level (p = 0.053) and increased p-Tau level (p = 0.056), respectively. CONCLUSION Patients with poor cognitive function have significantly lower vitreous humor levels of AD-related biomarkers Aβ40, Aβ42, and tTau. These biomarkers do not correlate with underlying eye conditions, suggesting their specificity in association with cognitive change. This is the first study to our knowledge to correlate cognition with AD-related proteins in the vitreous humor. Results suggest ocular proteins may have a role for early dementia detection in individuals at risk for AD.

Abstract
The authors report a new variant of idiopathic polypoidal choroidal vasculopathy (IPCV) in middle-aged Haitian men characterized by extramacular polypoidal lesions and bilateral extensive pigmentary alterations in the posterior pole in an annular wreath-like pattern surrounding the optic nerve and macular area. Two patients were seen at Massachusetts Eye and Ear Infirmary and one at Boston University Medical Center between 2010 and 2015. All three patients were middle-aged Haitian men who exhibited bilateral features of IPCV, including subretinal hemorrhages and serosanguinous pigment epithelial detachments. Indocyanine green angiography revealed extramacular polypoidal lesions located mostly along the major vascular arcades. Extensive pigmentary alterations were evident in the posterior pole surrounding the macula and optic nerve in an annular wreath-like pattern. These cases further expand the clinical spectrum of IPCV.

Abstract
BACKGROUND Neovascular age-related macular degeneration (AMD) is the leading cause of legal blindness in elderly populations of industrialised countries. Bevacizumab (Avastin®) and ranibizumab (Lucentis®) are targeted biological drugs (a monoclonal antibody) that inhibit vascular endothelial growth factor, an angiogenic cytokine that promotes vascular leakage and growth, thereby preventing its pathological angiogenesis. Ranibizumab is approved for intravitreal use to treat neovascular AMD, while bevacizumab is approved for intravenous use as a cancer therapy. However, due to the biological similarity of the two drugs, bevacizumab is widely used off-label to treat neovascular AMD. OBJECTIVES To assess the systemic safety of intravitreal bevacizumab (brand name Avastin®; Genentech/Roche) compared with intravitreal ranibizumab (brand name Lucentis®; Novartis/Genentech) in people with neovascular AMD. Primary outcomes were death and All serious systemic adverse events (All SSAEs), the latter as a composite outcome in accordance with the International Conference on Harmonisation Good Clinical Practice. Secondary outcomes examined specific SSAEs: fatal and non-fatal myocardial infarctions, strokes, arteriothrombotic events, serious infections, and events grouped in some Medical Dictionary for Regulatory Activities System Organ Classes (MedDRA SOC). We assessed the safety at the longest available follow-up to a maximum of two years. SEARCH METHODS We searched CENTRAL, MEDLINE, EMBASE and other online databases up to 27 March 2014. We also searched abstracts and clinical study presentations at meetings, trial registries, and contacted authors of included studies when we had questions. SELECTION CRITERIA Randomised controlled trials (RCTs) directly comparing intravitreal bevacizumab (1.25 mg) and ranibizumab (0.5 mg) in people with neovascular AMD, regardless of publication status, drug dose, treatment regimen, or follow-up length, and whether the SSAEs of interest were reported in the trial report. DATA COLLECTION AND ANALYSIS Two authors independently selected studies and assessed the risk of bias for each study. Three authors independently extracted data.We conducted random-effects meta-analyses for the primary and secondary outcomes. We planned a pre-specified analysis to explore deaths and All SSAEs at the one-year follow-up. MAIN RESULTS We included data from nine studies (3665 participants), including six published (2745 participants) and three unpublished (920 participants) RCTs, none supported by industry. Three studies excluded participants at high cardiovascular risk, increasing clinical heterogeneity among studies. The studies were well designed, and we did not downgrade the quality of the evidence for any of the outcomes due to risk of bias. Although the estimated effects of bevacizumab and ranibizumab on our outcomes were similar, we downgraded the quality of the evidence due to imprecision.At the maximum follow-up (one or two years), the estimated risk ratio (RR) of death with bevacizumab compared with ranibizumab was 1.10 (95% confidence interval (CI) 0.78 to 1.57, P value = 0.59; eight studies, 3338 participants; moderate quality evidence). Based on the event rates in the studies, this gives a risk of death with ranibizumab of 3.4% and with bevacizumab of 3.7% (95% CI 2.7% to 5.3%).For All SSAEs, the estimated RR was 1.08 (95% CI 0.90 to 1.31, P value = 0.41; nine studies, 3665 participants; low quality evidence). Based on the event rates in the studies, this gives a risk of SSAEs of 22.2% with ranibizumab and with bevacizumab of 24% (95% CI 20% to 29.1%).For the secondary outcomes, we could not detect any difference between bevacizumab and ranibizumab, with the exception of gastrointestinal disorders MedDRA SOC where there was a higher risk with bevacizumab (RR 1.82; 95% CI 1.04 to 3.19, P value = 0.04; six studies, 3190 participants).Pre-specified analyses of deaths and All SSAEs at one-year follow-up did not substantially alter the findings of our review.Fixed-effect analysis for deaths did not substantially alter the findings of our review, but fixed-effect analysis of All SSAEs showed an increased risk for bevacizumab (RR 1.12; 95% CI 1.00 to 1.26, P value = 0.04; nine studies, 3665 participants): the meta-analysis was dominated by a single study (weight = 46.9%).The available evidence was sensitive to the exclusion of CATT or unpublished results. For All SSAEs, the exclusion of CATT moved the overall estimate towards no difference (RR 1.01; 95% CI 0.82 to 1.25, P value = 0.92), while the exclusion of LUCAS yielded a larger RR, with more SSAEs in the bevacizumab group, largely driven by CATT (RR 1.19; 95% CI 1.06 to 1.34, P value = 0.004). The exclusion of all unpublished studies produced a RR of 1.12 for death (95% CI 0.78 to 1.62, P value = 0.53) and a RR of 1.21 for SSAEs (95% CI 1.06 to 1.37, P value = 0.004), indicating a higher risk of SSAEs in those assigned to bevacizumab than ranibizumab. AUTHORS' CONCLUSIONS This systematic review of non-industry sponsored RCTs could not determine a difference between intravitreal bevacizumab and ranibizumab for deaths, All SSAEs, or specific subsets of SSAEs in the first two years of treatment, with the exception of gastrointestinal disorders. The current evidence is imprecise and might vary across levels of patient risks, but overall suggests that if a difference exists, it is likely to be small. Health policies for the utilisation of ranibizumab instead of bevacizumab as a routine intervention for neovascular AMD for reasons of systemic safety are not sustained by evidence. The main results and quality of evidence should be verified once all trials are fully published.

Abstract
BACKGROUND The purpose of this paper is to study the differences between central subfield macular thickness (CSMT) measurements obtained by time-domain Stratus optical coherence tomography (OCT) and Cirrus spectral domain OCT (Carl Zeiss Meditec, Dublin, CA) and to formulate an equation to convert CSMT values from one to the other. METHODS CSMT were measured by both Stratus Macula OCT and Cirrus Macula OCT in 46 healthy subjects. Agreement between measurements was calculated using Lin's concordance coefficient. RESULTS The average age of our group was 30 with the logMAR visual acuity of -0.015. The Stratus CSMT measurement (mean ± standard deviation) 193.91 ± 21.7 was statistically significant from the Cirrus CSMT measurement 252.82 ± 28.4 (p < 0.001). The transformation equation 0.76×-0.51 from Cirrus to Stratus resulted in values that best agreed with the observed Stratus OCT values. CONCLUSIONS We identified a significant difference of CSMT measurements between Stratus and Cirrus. The Cirrus typically gave a higher value of CSMT. We derived a linear equation to convert the measurements from Cirrus to Stratus which resulted in transformed values that concord with the observed Stratus OCT values.

Abstract
PURPOSE To describe a case of successful treatment of acute retinal necrosis with a combination of antivirals and intravenous immunoglobulin. METHODS This is a case report of a 77-year-old white man diagnosed with unilateral acute retinal necrosis. RESULTS Combination therapy with systemic antivirals, prophylactic laser retinopexy, and intravenous immunoglobulin halted progression of retinitis and preserved visual acuity. CONCLUSION Acute retinal necrosis is an aggressive disease with significant risk of vision loss even when treated with appropriate therapy. In this report, the authors describe a case of successful treatment with a combination of systemic antivirals and intravenous immunoglobulin. Intraocular antiviral injection plus systemic treatment remain to be a more cost-effective option.

Abstract
BACKGROUND/AIMS [corrected] The purpose of this study was to determine the incidence of, and risk factors dictating, progression of subclinical macular oedema (SCME) to clinically significant macular oedema (CSME) in patients with diabetes. METHODS This was a retrospective, observational case-controlled study at the Veterans Administration (VA) Boston Healthcare System. The study group included subjects with central subfield macular thickness (CSMT) of 200-300 μm, measured by optical coherence tomography, compared with a control group with foveal thickness of <200 μm, matched for age, sex and duration of diabetes. Main outcomes measured were progression to CSME by clinical examination. RESULTS A total 124 eyes of 73 diabetic patients from the greater Boston area were included in this retrospective study. The study group comprised 52 eyes of 37 diabetic patients with SCME in one or both eyes. The control group included 72 eyes of 36 patients without macular oedema. Sixteen eyes of 13 subjects (35%) progressed to CSME in the study group, compared with six eyes of four subjects (11%) in the control group. Stepwise logistic regression analysis confirmed that prior history of CSME increased the risk of progression (OR 3.69, CI 1.10 to 12.31, p=0.03). Logistic regression analysis also depicted a 15% increase in odds of progression with each 10 μm increase in CSMT (OR 1.15, CI 1.03 to 1.28, p=0.01). CONCLUSIONS The results and statistical analyses of this retrospective study suggest that a significant number of patients with SCME ultimately progress to CSME compared with controls. A significant association with prior history of CSME, advancing age and graded increases in CSMT was found.

Abstract
The development of acute retinal necrosis (ARN) is not uncommon among individuals with a history of herpes simplex encephalitis, as the virus may be capable of transport via axonal cells to the neuroretina. Though it is known that ARN severely threatens vision, timely initiation of effective therapy can help save a patient's vision and retina. In this case report, clinical resistance to acyclovir was found. Subsequent treatment with intravitreal foscarnet resulted in immediate clinical improvement. This case suggests that patients with acute retinal necrosis can be considered for treatment with intravitreal foscarnet in the setting of systemic acyclovir resistance.

Abstract
PURPOSE To report early outcomes of a prospective, double-masked, controlled trial comparing bevacizumab (Avastin; Genentech Inc, South San Francisco, California, USA) to ranibizumab (Lucentis; Genentech Inc) for the treatment of age-related macular degeneration. DESIGN Prospective, double-masked, randomized clinical trial. METHODS This is a single-center, randomized clinical trial at the Boston Veterans Affairs Healthcare System. Patients who met inclusion criteria were randomized 2:1 to bevacizumab or ranibizumab. Each patient contributed 1 eye to the study. All subjects and investigators (except for the pharmacist responsible for study assignments) were masked to treatment arms. Visual acuity (VA) was checked on Early Treatment Diabetic Retinopathy Study (ETDRS) chart. Patients were given either bevacizumab or ranibizumab every month for the first 3 months, followed by optical coherence tomography-guided, variable-dosing schedule. Main outcomes measured were VA and foveal thickness. RESULTS Twenty patients completed the 6-month follow up. Thirteen patients received bevacizumab and 7 patients received ranibizumab. No subjects in either group lost more than 15 letters on ETDRS chart. The average preoperative VA was 31.6 letters in the bevacizumab group and 30.4 letters in the ranibizumab group. At 6 months follow-up, mean vision was 46.4 letters in the bevacizumab group and 37.4 letters in the ranibizumab group. Two-tailed ttest failed to show statistical significance between the two groups. Patients in the bevacizumab group underwent an average of 5 injections, while patients in the ranibizumab group underwent a mean of 4 injections. CONCLUSION Early results of a head-to-head, randomized, double-masked, prospective, single-center controlled trial between bevacizumab and ranibizumab show no difference in efficacy between the two treatments for choroidal neovascularizaton in the treatment of age-related macular degeneration. As this study conveys results of a small number of patients, further studies with larger sample sizes are needed in order to establish statistical significance.

Abstract
Objective To evaluate the clinical and angiographic incidence of cystoid macular edema (CME) after cataract surgery, and to determine the impact of intraoperative triamcinolone acetonide. Methods This is a prospective, single-center trial looking at 81 eyes of 61 patients who underwent clear-cornea incision phacoemulsification with lens implantation under topical anesthesia by a single surgeon. Outcome measures included clinical and angiographic CME, the impact of operative time, medications, and systemic disease on the presence of CME. Results Eight eyes (9.87%) demonstrated angiographic CME at the one-week and six-week follow-up visits. Two eyes showed evidence of clinical CME (2.46%) on examination. Subjects with diabetes had an increased risk of angiographic CME. Conclusion The incidence of clinically significant and angiographic CME in this study is confirmatory of previous studies in the literature. The use of intraoperative subconjunctival triamcinolone acetonide did not appear to significantly reduce the development of post-operative CME.

Abstract
Introduction The veteran population presents unique challenges in the management of vitreoretinal disorders. We compiled the surgical outcomes for the most common visually significant vitreoretinal diagnoses. Those results were then compared to visual and anatomic outcomes established in the literature. Materials and Methods Medical records over a three-year time period, from January 2005 through December 2007, were reviewed for 208 persons who underwent vitreoretinal surgery for vitreous hemorrhage, retained lens fragment, rhegmatogenous and tractional retinal detachment, macular hole, and macular pucker at the Jamaica Plain Campus of the Veterans Affairs Boston Healthcare System in Boston, MA. A comprehensive search of the literature was conducted on Medline. Data from several large case series and meta-analyses were compared to results obtained at the VA Boston. Results A total of 208 veterans underwent vitreoretinal surgery from January 2005 to December 2007. After excluding those with rare diagnoses and lack of adequate follow-up data, the outcomes of 181 vitreoretinal procedures were included in this study. Discussion Overall, veterans at a regional referral center in Boston demonstrate postoperative visual and anatomic outcomes comparable to outcomes reported in the ophthalmic literature.

Abstract
BACKGROUND AND OBJECTIVE To determine the visual outcome of laser treatments for macular edema due to branch retinal vein occlusion (BRVO) in patients with a preoperative visual acuity (VA) of 20/200 or worse compared to patients with a preoperative VA of better than 20/200. PATIENTS AND METHODS Records of 88 patients with macular edema secondary to BRVO undergoing laser treatment from 1984 to 2003 were reviewed. Mean VA was measured before and after each treatment and after the final treatment. RESULTS All patients received between one and five laser treatments. Preoperative VA was better than 20/200 in 56 patients (group 1) and 20/200 or worse in 32 patients (group 2). Patients in group 1 had a mean improvement of 0.48 lines and 57% had a final VA of 20/40 or better. Patients in group 2 had a mean improvement of 1.69 lines and 20% had a final VA of 20/40 or better. CONCLUSIONS Patients with poor VA (20/200 or worse) secondary to macular edema due to BRVO responded positively to laser treatment. The level of preoperative VA can be a useful predictor of visual outcome. These patients should consider laser treatment before alternative, more aggressive approaches.

Abstract
BACKGROUND AND OBJECTIVE To describe a series of patients with decreased vision secondary to stage 1 macular hole confirmed by optical coherence tomography (OCT) that failed to spontaneously resolve with observation. To determine whether current surgical techniques can prevent progression to a full-thickness macular hole and lead to improved visual acuity. PATIENTS AND METHODS Retrospective, comparative case series presenting patient demographics, duration of symptoms, timing of surgery, preoperative and postoperative vision, and clinical outcome based on examination and OCT. RESULTS Five eyes of five patients with stage 1 macular holes identified on OCT required surgical repair. All eyes showed anatomic closure and lack of progression to a full-thickness hole confirmed by OCT after one procedure. Mean preoperative visual acuity was 20/102 (range, 20/50 to 20/200) and mean postoperative visual acuity was 20/52 (range, 20/25 to 20/200). Average improvement for all five eyes was 3 Snellen lines, with four of the five (80%) improving 5 lines each. CONCLUSION In symptomatic eyes with stage 1 macular holes that fail to spontaneously resolve with observation, vitrectomy with intraocular gas tamponade may prevent progression to a full-thickness hole and lead to improved visual acuity.

Abstract
PURPOSE To report the visual outcome of multiple laser treatments for macular edema attributable to branch retinal vein occlusions (BRVO) and to determine if any prognostic factors exist for improvement. DESIGN Retrospective chart review. METHODS A private practice with four vitreoretinal surgeons performed laser treatments on 88 eyes of 88 patients with macular edema secondary to BRVO from 1984 to 2003. Mean preoperative and postoperative visual acuities were collected after each laser treatment. Final visual acuities were also documented. RESULTS All 88 patients received at least one laser treatment, and 46 patients of the initial 88 underwent multiple treatments. Overall, forty-one (46.6%) of the total 88 patients improved by 2 or more lines, whereas 33 patients (37.5%) were within 1 line of the preoperative vision, and 14 patients (15.9%) worsened by 2 or more lines. The mean final visual improvement was 0.92 lines for all 88 patients. The group of patients that responded favorably to the first laser treatment (n = 37) showed an overall improvement of 3.5 lines. However, patients who responded poorly to the first laser treatment resulted in an overall worsening of vision by 0.96 lines. CONCLUSIONS Our study found that multiple laser treatments can improve visual acuity and resolve macular edema and that each additional laser treatment gives a patient a modest chance of visual improvement. A positive or stable visual response to first laser treatment portends a favorable prognosis with subsequent laser treatments.

Abstract
Transpupillary thermotherapy has recently emerged as a therapeutic option for patients with numerous posterior segment disorders. During the past decade, it has been used for the management of benign and malignant tumors, either as sole therapy or in combination with other treatments such a plaque radiotherapy. More recently, it has been used for management of choroidal neovascularization (CNV) secondary to age-related macular degeneration. A prospective, randomized, sham-controlled multicenter clinical trial (TTT4CNV) is currently underway to evaluate the effectiveness of TTT for the management of CNV.
